In addition, you can set custom ``key:value`` metadata for use by your applications. For a discussion of specific metadata properties, see the `metadata concept page `_. There are two ways to set metadata on objects: - At upload time you can specify one or more metadata properties to associate with objects, using the ``gsutil -h option``. For example, the following command would cause gsutil to set the ``Content-Type`` and ``Cache-Control`` for each of the files being uploaded from a local directory named ``images``: gsutil -h "Content-Type:text/html" \ -h "Cache-Control:public, max-age=3600" cp -r images \ gs://bucket/images Note that -h is an option on the gsutil command, not the cp sub-command. - You can set or remove metadata fields from already uploaded objects using the ``gsutil setmeta`` command. See "gsutil help setmeta". SETTABLE FIELDS; FIELD VALUES You can't set some metadata fields, such as ETag and Content-Length. The fields you can set are: - ``Cache-Control`` - ``Content-Disposition`` - ``Content-Encoding`` - ``Content-Language`` - ``Content-Type`` - ``Custom-Time`` - Custom metadata Field names are case-insensitive. All fields and their values must consist only of ASCII characters, with the exception of values for ``x-goog-meta-`` fields, which may contain arbitrary Unicode values. Note that when setting metadata using the XML API, which sends custom metadata as HTTP headers, Unicode characters are encoded using UTF-8, then url-encoded to ASCII. For example: gsutil setmeta -h "x-goog-meta-foo: ã" gs://bucket/object stores the custom metadata key-value pair of ``foo`` and ``%C3%A3``. Subsequently, running ``ls -L`` using the JSON API to list the object's metadata prints ``%C3%A3``, while ``ls -L`` using the XML API url-decodes this value automatically, printing the character ``ã``. VIEWING CURRENTLY SET METADATA You can see what metadata is currently set on an object by using: gsutil ls -L gs://the_bucket/the_object c F\rSrSrSr\R "S/SQSS\0S9rSr g ) CommandOptionsUrmetadata)z cache-controlcachingz content typez mime typemimetypeadditional_helpzWorking With Object Metadata) help_namehelp_name_aliases help_typehelp_one_line_summary help_textsubcommand_help_textN) __name__ __module__ __qualname____firstlineno____doc__rHelpSpec_DETAILED_HELP_TEXT help_spec__static_attributes__r*platform/gsutil/gslib/addlhelp/metadata.pyr r Us-.##":#)r!r N) r __future__rrrrgslib.help_providerrrr rr!r"r%s.-&%',:z\r!
